Ok guys lets see if you know the answer to this one cuss I dont!! When Im in a parking lot or stuck in freeway traffic jam travling about 5mph or so my 83 Clieca Supra tends to decelerite while im still holding the gas down and then hops back on as if it never happend and then does it over and over. What can I do to fix this can it be the throttle body senser?? Or just a bad clutch??
